FAQ

Q1: What is the main difference between Hastelloy B-2 and Hastelloy C-276?
A1: Hastelloy B-2 is optimized for reducing environments such as hydrochloric acid, while C-276 is designed for oxidizing and mixed environments like sulfuri .

 

Q2: Can Hastelloy B-2 be used in oxidizing acids or ferric chloride environments?
A2: Not recommended. Hastelloy B-2 can suffer rapid corrosion in oxidizing environments. It performs best in pure reducing conditions.

 

Q3: What is the typical working temperature range?
A3: Hastelloy B-2 performs well from ambient to around 800°C (1470°F), depending on service conditions.

 

Q4: Do you provide customized sizes or machining service for rings?
A4: Yes. We offer custom cutting, CNC machining, and heat treatment according to your drawings or dimensional requirements.

 

Q5: What inspection or certificates are available?
A5: Each batch can be supplied with EN 10204 3.1 / 3.2 certificate, including chemical composition, mechanical properties, and NDT test results.

 

Q6: What packaging and delivery terms do you provide?
A6: Standard export seaworthy packaging with plastic film and wooden cases. Delivery time depends on stock-usually within 7-15 days for standard sizes.

 

Q7: What is the delivery time?
A7: Usually 7-15 working days for stock materials, and 20-30 days for custom-machined or special-size rings.

 

Q8: Do you offer price discounts for large quantities?
A8: Yes. We provide big price discounts for bulk orders or long-term cooperation projects. Please contact us for a detailed quotation.
